Description

Technical Field

[0001] This utility model relates to the field of underground utility tunnel construction technology, specifically to a comprehensive utility tunnel. Background Technology

[0002] The application of integrated utility tunnels is becoming increasingly widespread in urban infrastructure construction. The pressure pipelines entering the existing integrated utility tunnels are mainly water supply pipes. Due to their good water quality, and the fact that the air vent valves and sludge discharge valves are installed on the pipelines inside the tunnel, the air venting and sludge discharge operations are carried out inside the tunnel, minimizing the impact on the tunnel environment and natural water bodies.

[0003] However, in recent years, various regions have attempted to introduce sewage pipelines into integrated utility tunnels, leading to an increase in the laying of pressurized sewage pipelines. Sewage contains toxic, harmful, and flammable gases. If air vents and sludge discharge valves are installed directly on the pipelines within the tunnel, just like water supply pipes, the air vents will disrupt the air environment of the tunnel and threaten fire safety; the sludge discharge will pollute the interior of the tunnel, and the muddy water discharged into rivers via drainage pump pits will also pollute natural water bodies. The original air vent and sludge discharge design is not suitable for pressurized sewage pipelines. In addition, when converting pressurized sewage flow pipes within integrated utility tunnels to gravity flow pipes, there is a lack of suitable energy dissipation component designs, affecting the stable operation of the sewage pipeline system.

[0004] Therefore, in order to ensure the safe operation of sewage pipelines within the integrated utility tunnel and avoid environmental pollution, it is urgent to design new exhaust and sludge discharge schemes and energy dissipation components. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated utility tunnel, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a comprehensive utility tunnel, comprising: a sewage tank, a sewage pressure pipe, a sewage gravity pipe, an exhaust system, a sludge discharge system, and an energy dissipation system.

[0007] The sewage tank extends along a first direction, and a sewage channel is defined within the sewage tank. The sewage tank includes a main body section and a partially widened section. The partially widened section is located on one side of the main body section, and the cross-sectional area of ​​the sewage channel at the partially widened section is larger than the cross-sectional area of ​​the main body section.

[0008] The energy dissipation component is located at the locally widened portion within the sewage channel. The energy dissipation component includes two energy dissipation pools that are sequentially connected and communicated along a first direction. The two energy dissipation pools have inlets and outlets on opposite sides along the first direction, respectively. The sewage pressure pipe and the sewage gravity pipe are both located within the sewage channel, with one end of the sewage pressure pipe connected to the inlet and one end of the sewage gravity pipe connected to the outlet.

[0009] The exhaust assembly and the sludge removal assembly are respectively located at the main body section.

[0010] The exhaust assembly includes an exhaust well and an exhaust pipe. The exhaust well is located at the top of the main body, and the two ends of the exhaust pipe are respectively connected to the sewage pressure pipe and the exhaust well.

[0011] The sludge discharge assembly includes: sludge discharge wells and sludge discharge pipes. The sludge discharge wells are spaced apart on the outside of the main body section, and the two ends of the sludge discharge pipes are respectively connected to the sewage pressure pipe and the sludge discharge wells.

[0012] As a preferred technical solution, the locally widened portion is connected to the main body section through a transition section on both sides along the first direction, and the cross-sectional area of ​​the sewage channel in the transition section gradually decreases from one end near the locally widened portion to the other end.

[0013] As a preferred technical solution, multiple energy dissipation stones are evenly laid at the bottom of the energy dissipation tank near the sewage pressure pipe. An overflow wall is provided between the two energy dissipation tanks. There is a gap between the top of the overflow wall and the top of the local widening section. Several flow holes are opened on the overflow wall. The two energy dissipation tanks are connected through the overflow wall.

[0014] As a preferred technical solution, the height of the overflow wall is 30% to 35% of the height of the energy dissipation pool.

[0015] As a preferred technical solution, the height of the overflow wall is 1200-1400mm.

[0016] As a preferred technical solution, the bottom of both energy dissipation pools is covered with a concrete pad, and the energy dissipation stones are laid on the concrete pad.

[0017] As a preferred technical solution, the energy dissipation component further includes a bend, which is connected to one end of the sewage pressure pipe, and the end of the bend away from the sewage pressure pipe is inclined towards the bottom of the energy dissipation tank.

[0018] As a preferred technical solution, the energy dissipation component further includes an inspection well, which is located at the top of the partially widened portion and is connected to an energy dissipation pool.

[0019] As a preferred technical solution, the exhaust assembly further includes an exhaust valve, which is connected to the exhaust pipe and is used to control the connection between the exhaust pipe and the exhaust well.

[0020] As a preferred technical solution, the sludge discharge assembly further includes a sludge discharge valve, which is located at one end of the sludge discharge pipe and is used to control the connection between the sludge discharge pipe and the sludge discharge well.

[0021] The integrated utility tunnel provided by the above technical solution has the following advantages compared with the existing technology:

[0022] 1. By installing exhaust and sludge removal components in the sewage tank of the integrated utility tunnel, the gas and sludge in the sewage pressure pipe are led out to the outside of the sewage tank for discharge, thus avoiding pollution and damage to the environment inside the tank.

[0023] 2. At the connection between the sewage pressure pipe and the sewage gravity pipe in the sewage tank, the tank body is widened to form a local widening section, and an energy dissipation component is installed here. The energy dissipation component is used to dissipate the energy of the sewage flowing out of the sewage pressure pipe before it is discharged into the sewage gravity pipe, so as to avoid water flow impact causing damage to the pipe body and ensure the stable operation of the sewage pipeline system.

For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0043] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0044] Please see Figure 1-7The integrated utility tunnel provided in this application embodiment includes: a sewage tank 1, a sewage pressure pipe 2, a sewage gravity pipe 3, an exhaust assembly 4, a sludge discharge assembly 5, and an energy dissipation assembly 6.

[0045] The sewage tank 1 extends along a first direction, and a sewage channel 11 is defined inside the sewage tank 1. The sewage tank 1 includes a main body section 12 and a partially widened section 13. The partially widened section 13 is located on one side of the main body section 12, and the cross-sectional area of ​​the sewage channel 11 at the partially widened section 13 is larger than the cross-sectional area at the main body section 12.

[0046] The energy dissipation component 6 is located at the partially widened portion 13 within the sewage channel 11. The energy dissipation component 6 includes two energy dissipation pools 61 connected and linked sequentially along a first direction. The two energy dissipation pools 61 have inlets 62 and outlets 63 on opposite sides along the first direction, respectively. The sewage pressure pipe 2 and the sewage gravity pipe 3 are both located within the sewage channel 11, with one end of the sewage pressure pipe 2 connected to the inlet 62 and one end of the sewage gravity pipe 3 connected to the outlet 63.

[0047] The exhaust assembly 4 and the sludge removal assembly 5 are respectively located at the main body section 12.

[0048] The exhaust assembly 4 includes an exhaust well 41 and an exhaust pipe 42. The exhaust well 41 is located at the top of the main body, and the two ends of the exhaust pipe 42 are respectively connected to the sewage pressure pipe 2 and the exhaust well 41.

[0049] The sludge discharge assembly 5 includes a sludge discharge well 51 and a sludge discharge pipe 52. The sludge discharge well 51 is spaced apart on the outside of the main body section 12. The two ends of the sludge discharge pipe 52 are respectively connected to the sewage pressure pipe 2 and the sludge discharge well 51.

[0050] In this embodiment, the gas in the pipes inside the sewage tank 1 is led to the exhaust well 41 through the exhaust pipe 42. The top of the exhaust well 41 is flush with the ground and connected to the outside, thereby venting the gas in the pipes to the atmosphere and preventing the gas from being directly released into the sewage tank 1, which would damage the environment inside the tank. The sludge in the pipes inside the sewage tank 1 is led to the sludge discharge well 51 through the sludge discharge pipe 52. The sludge discharge well 51 is connected to the outside, thereby discharging the sludge in the pipes to the outside and preventing the sludge from being directly discharged into the sewage tank 1 and causing pollution. Energy dissipation components 6 are installed in the locally widened section 13 of the sewage tank 1. The inlet 62 and outlet 63 of the energy dissipation components 6 are connected to the sewage pressure pipe 2 and the sewage gravity pipe 3, respectively. The water flow in the sewage pressure pipe 2 enters the two energy dissipation pools 61 through the inlet 62 for energy dissipation. After energy dissipation, it flows into the sewage gravity pipe 3 through the outlet 63. This effectively prevents high-speed water flow from directly impacting the sewage gravity pipe 3 and related facilities, causing pipe wear, loosening of joints, or even pipe rupture and other damage, affecting the normal operation and structural safety of the integrated utility tunnel. Furthermore, the energy dissipation components 6 allow the sewage in the pressure pipe to enter the sewage gravity pipe 3 at a suitable flow rate and flow pattern, avoiding instability of the sewage gravity pipe 3 due to excessive water flow energy, ensuring the normal operation of the sewage gravity pipe 3, and allowing the sewage to flow smoothly under gravity, preventing problems such as sewage backflow and siltation.

[0051] It is worth noting that, in order to prevent the direct emission of toxic and harmful gases from the sewage pressure pipe 2 from polluting the external environment, a gas purification component can be installed in the exhaust well 41. The toxic and harmful gases can be purified before being emitted, which is beneficial to environmental protection.

[0052] In some embodiments, the partially widened portion 13 is connected to the main body section 12 via a transition section 14 on each side along the first direction, and the cross-sectional area of ​​the sewage channel 11 in the transition section 14 gradually decreases from one end near the partially widened portion 13 to the other end. By setting the transition section 14, the internal space of the sewage tank 1 is increased, which is beneficial for better accommodating the energy dissipation component 6 and provides sufficient installation space for related facilities.

[0053] In some embodiments, multiple energy dissipation stones 610 are evenly laid at the bottom of the energy dissipation tank 61 near the sewage pressure pipe 2, and an overflow wall 611 is provided between the two energy dissipation tanks 61. There is a gap between the top of the overflow wall 611 and the top of the partial widening portion 13, and several flow holes 6110 are opened on the overflow wall 611. The two energy dissipation tanks 61 are connected through the overflow wall 611.

[0054] In this embodiment, energy dissipation stones 610 are evenly laid at the bottom of the energy dissipation tank 61 near the sewage pressure pipe 2 to dissipate the sewage entering the tank for the first time. After the first energy dissipation, the sewage undergoes a second energy dissipation through the overflow hole 6110 on the overflow wall 611 and then enters another energy dissipation tank 61 for buffering. After buffering, it flows into the sewage gravity pipe 3 through the outlet 63.

[0055] It is worth noting that when the sewage flow rate is small, the sewage, after energy dissipation, enters the second energy dissipation tank 61 through the overflow hole 6110 and is discharged into the sewage gravity flow pipe; when the sewage flow rate is large, the sewage, after energy dissipation, overflows into the second energy dissipation tank 61 through the gap between the overflow hole 6110 and the top of the overflow wall 611 and is discharged into the sewage gravity flow pipe.

[0056] To further ensure the energy dissipation effect of the overflow wall 611, in some embodiments, the height of the overflow wall 611 is set to 30% to 35% of the height of the energy dissipation pool 61. Specifically, the height of the overflow wall 611 is 1200 to 1400 mm. On the one hand, this height ensures that excess water can be smoothly discharged under conditions such as design floods, preventing the water level in the energy dissipation pool 61 from becoming too high and overflowing. It also helps to form a good water flow pattern, so that the water flow is evenly distributed in the energy dissipation pool 61, avoiding undesirable flow patterns such as flow deviation and backflow. On the other hand, this height increases the water drop distance, allowing the water flow to mix fully with the air, and using the turbulence and collision of the water flow to consume more energy. Furthermore, it enables the water flow to form a stable hydraulic jump in the energy dissipation tank 61, and ensures that the hydraulic jump occurs at an appropriate location within the energy dissipation tank 61, fully utilizing the energy dissipation effect of the hydraulic jump to improve energy dissipation efficiency. On the other hand, the height of the overflow wall 611 is the optimal height, taking into full account the structural load-bearing capacity of the wall itself, ensuring that the wall can be safely and stably maintained under various working conditions, without overturning, sliding, or other damage. Moreover, the overflow wall 611 at this height will not affect other buildings or facilities within the sewage tank 1, ensuring the safe operation of the entire integrated pipe gallery system. In addition, this height provides sufficient space for later operation, maintenance, and repair, facilitating the inspection, repair, and maintenance of the equipment within the overflow wall 611 and the energy dissipation tank 61 by staff.

[0057] During the operation of the energy dissipation component 6, the water flow possesses significant energy, which can scour the bottom of the pool, affecting the stability of the foundation. Furthermore, the foundation at the bottom of the pool is prone to uneven settlement due to uneven pressure. Therefore, in some embodiments, a concrete cushion layer 612 is laid at the bottom of both energy dissipation pools 61, and the energy dissipation stones 610 are laid on top of the concrete cushion layer 612. The concrete cushion layer 612 provides a flat and solid foundation surface for the construction of the bottom of the energy dissipation pool 61, facilitating construction within the energy dissipation pool 61.

[0058] It is worth noting that in actual construction, the thickness of the concrete cushion layer 612 inside the energy dissipation pool 61 must be ensured. On the one hand, the concrete cushion layer 612 needs to be thick enough to withstand water flow pressure and other loads, preventing damage due to insufficient strength. On the other hand, a concrete cushion layer 612 with a certain thickness can better resist the scouring and abrasion of water flow, maintaining good impact and wear resistance during long-term operation and extending the service life of the energy dissipation pool 61. In addition, an appropriate thickness allows the concrete cushion layer 612 to adapt to minor deformations of the foundation to a certain extent. When uneven settlement or other deformations occur in the foundation, the cushion layer can buffer and adjust through its own deformation, reducing the impact on the overall structure of the energy dissipation pool 61 and preventing excessive stress and cracks in the structure due to foundation deformation. Furthermore, the inventors determined through multiple experiments that the thickness of the concrete cushion layer 612 should be set to ≥500mm to ensure the above effects and extend the service life of the energy dissipation component 6.

[0059] In some embodiments, the energy dissipation component 6 further includes a bend 64 connected to one end of the sewage pressure pipe 2, with the end of the bend 64 away from the sewage pressure pipe 2 inclined towards the bottom of the energy dissipation tank 61. The bend 64 ensures that the sewage in the sewage pressure pipe 2 can flow sufficiently onto the energy dissipation stone 610 for the first energy dissipation, guaranteeing the effectiveness of the first energy dissipation. This prevents excessive water flow at the inlet 62 from overflowing the overflow wall 611, causing the water to enter the second energy dissipation tank 61 directly without energy dissipation, and then discharge from the outlet 63 into the sewage gravity pipe 3, thus impacting and damaging the sewage gravity pipe 3. In addition, in some embodiments, the angle between the bend 64 and the side wall of the energy dissipation pool 61 is R, 30°≤R≤60°, ensuring that the angle between the bend 64 and the side wall of the energy dissipation pool 61 is between 30° and 60°. This is the optimal angle obtained by the inventors through multiple experiments, which can ensure that all water flows onto the energy dissipation stone 610.

[0060] In some embodiments, the energy dissipation assembly 6 further includes an inspection well 65, which is located at the top of the partial widening portion 13 and communicates with an energy dissipation pool 61. When maintenance of the energy dissipation assembly 6 is required, personnel can enter the energy dissipation pool 61 through the inspection well 65 to inspect and maintain it, which is very inexpensive.

[0061] In some embodiments, the venting assembly 4 further includes a venting valve 43 connected to the venting pipe 42, which controls the connection between the venting pipe 42 and the venting well 41. The sludge discharge assembly 5 further includes a sludge discharge valve 53 located at one end of the sludge discharge pipe 52, which controls the connection between the sludge discharge pipe 52 and the sludge discharge well 51. The valves effectively control the venting and sludge discharge of the pipes within the sewage tank 1. When personnel need to enter the venting well 41 or the sludge discharge well 51 for maintenance work, the valves can be closed accordingly, providing a good working environment and ensuring personnel safety.

[0062] It is worth noting that, in order to ensure the sealing and waterproofing of the sewage pressure pipe 2 and sewage gravity pipe 3 when they pass through the wall, prevent leakage, provide certain support and protection for the pipes, reduce the risk of deformation and cracking caused by uneven stress, and extend the service life of the pipes, a waterproof sleeve is installed at the connection between the pipes and the wall.

[0063] In summary, the integrated utility tunnel provided in this embodiment can ensure the safe operation of the pipelines in the sewage tank 1, avoid pollution and damage to the environment, and better adapt to the development of integrated utility tunnels.
